Thank you. I will try to do that. I'll have to learn how to strace first, though. Sorry, that was the reason why I did not already strace it (you suggested it already in a previous message, thanks! Sorry for not having followed your advice in the first place). > If you see any reads/writes to the sockets outside the handshake section > of the code, you'll have found the culprit. Ok, thanks. Hopefully, I'll have time to do it tomorrow...
